There's a lots of websites out there, sharing grabber scripts. I meant just install a script and you can have someones whole data. My personal site is based on Youtube API3 and our developer designed it to download videos from youtube.
But, the problem is, If someone wrote another script to stole my data, I mean grab my site's content with php curl or something, how can I stop him?
I can detect and block a single IP, but that's not the best solution. Please help me with some code's what we can put directly into our .htaccess file or somewhere to stop grabbing our content.
